What's new in this version:

libpurple
o Fix --disable-avahi to actually disable it in configure, as opposed to just making the warning non-fatal.
o Fix using GNOME proxy settings properly. (Erik van Pienbroek)

IRC
o Fix parsing of invalid TOPIC messages. (CVE-2009-2703)

MSN
o Sending custom smileys in chats is now supported.

o Fix connecting to XMPP domains with no SRV records from Pidgin on Windows.
o Fix typing notifications with Pidgin 2.5.9 or earlier.
o Fix connecting using BOSH and legacy authentication (XEP-0078).
o Adding buddies of the form "romeo@…/Resource" are handled properly. In addition, it is no longer possible to add buddies of the form "room@…/User", where room@… is a MUC.
o Don't crash when receiving "smileyfied" XHTML-IM from clients that don't support bits of binary (ie. when getting an empty <data/> in return)

Yahoo!/Yahoo! JAPAN
